BackgroundInterleukin-2 receptor antagonists have supplanted polyclonal antibody preparations as the most frequently used induction agents after lung transplantation, but the relative efficacy of these agents has not been firmly established.MethodsWe retrospectively analyzed the efficacy of basiliximab compared with antithymocyte globulin among 157 adult lung transplant recipients at our center.ResultsAt 3, 6, and 12 months after transplantation, the median cumulative acute rejection A scores for the basiliximab group (2, 2, and 3, respectively) were significantly higher than those for the anti-thymocyte globulin group (1, 1, and 2, respectively; p = 0.003, 0.004, and 0.033, respectively). In addition, basiliximab recipients were more likely to develop acute rejection grade > or = A2 than anti-thymocyte globulin recipients; in fact, 60% of basiliximab recipients compared with 38% of anti-thymocyte globulin recipients developed their first episode of acute rejection grade > or = A2 in the first 100 days after transplantation (log-rank p = 0.04). Furthermore, basiliximab recipients were more likely to develop bronchiolitis obliterans syndrome than anti-thymocyte globulin recipients (log-rank p = 0.036). Two years after transplantation, 36% of basiliximab recipients and 26% of anti-thymocyte globulin recipients developed bronchiolitis obliterans syndrome. However, there were no significant differences in the incidences of cytomegalovirus viremia and pneumonitis between the 2 groups (p = 0.86 and 0.89, respectively).ConclusionsInduction with anti-thymocyte globulin is associated with a lower burden of acute rejection and bronchiolitis obliterans syndrome compared with basiliximab, without a significant difference in the incidence of cytomegalovirus infections.
